Exhaust issues

So I have a dilemma here. I have motordyne art pipes and a motordyne midback. I had that on with the stock y pipe and it was decently loud but it had a bit of rasp at 3k. My problem is I bought a Megan y pipe temporarily so that I could save up for the Xyz pipe but it sounds a lot quieter and doesn’t have the nice tone it had before. Is it normal for any y pipe to quiet an exhaust down or is it because I didn’t get the Xyz pipe?

It's almost impossible to predict what will happen when you mix/match exhaust pieces. It's also incredibly difficult to try to theorize fluid dynamics outside of complicated simulation software.

The "trial and error" method is what a lot of folks rely on with exhaust modifications, some folks prefer the "tried and true" method as well.

Math is hard.

Damn that hurts 😥. Do you know any good catback systems by chance? I really want to have a more aggressive and louder sound. I don’t want ear piercing loud but something that’ll let the boys know I’m a block away if you get what I mean

You have it... you have a Motordynr exhaust. Anything louder is ignorant loud.

Lmao ok you guys are right. I’ll just stick to the plan and save up for the Xyz pipe. I drove from Cali to Vegas just to pick up the mid back cause it’s so rare and to get rid of it would be nonsense
